Two scales for the same thing

Converts minutes per kilometre into kilometres an hour and back, and gives the resulting 5K and marathon times.

A treadmill shows speed in kilometres an hour, a watch shows pace in minutes per kilometre, and the training plan is written in pace. The conversion is inverse — the faster you go, the smaller the pace number — and heads do it badly.

One useful anchor: twelve kilometres an hour is exactly five minutes per kilometre. From there it is easy — ten km/h is six minutes, fifteen is four.

What this calculator shows

Pace in minutes per kilometre and per mile
Speed in kilometres an hour and miles an hour
The 5K and marathon times that pace would produce

What to keep in mind

The conversion is linear and assumes one pace held throughout. No one runs a marathon at 5K pace.
A mile is taken as 1,609.344 metres, the international definition.

FAQs

How do I convert pace to speed?

Divide 3,600 by the pace in seconds per kilometre. A 5:00 pace, or 300 seconds, is exactly 12 kilometres an hour.

What pace is good for an amateur?

6:00 to 6:30 per kilometre is a solid beginner, 5:00 to 5:30 marks regular training. Under 4:30 over long distances belongs to trained runners.

Why does treadmill pace not match the road?

A treadmill has no air resistance and the belt moves for you. Setting a one percent incline brings the effort closer to running outdoors.

How do I get pace per mile?

Multiply the kilometre pace by 1.609. A 5:00 per kilometre pace is 8:03 per mile.

Worked example

Five thirty pace

Input: 5:30 per kilometre

Output: 10.91 km/h, a 5K in 27:30

Note: A marathon at that pace would take 3:52:04 — assuming the pace holds for all forty-two kilometres. In practice a marathon like that needs a considerably faster 10K.
